The day one of my colleagues disappeared

I was having lunch and when I returned to work there was a very strange feeling in the air in the office. Something was not right. I was very soon to find out what had happened when I was out for lunch. My colleagues told me that the police had shown up and arrested one of my colleagues. I thought to myself is this a joke? Soon enough I realised it was true.
Eh, OK why did they arrest him...?
His desk was empty and it was just as he had left it. Soon we got the full picture. We had access to customers credit card details and someone in the office had been printing them out and sold the details to people who had bought computers and so on. This was found out by the company´s security and this was put under surveillance by one of our colleagues who checked all of us = who took the printed papers from the printer. So, I was a suspect! Well, at least for a while. As I remember taking my own printouts and I saw these printouts and I didn´t really think so much about them. Luckily I did not take one by mistake! Then I really would be under suspicion. Well, my colleague got prison for fraud and he never returned to work. That was the day my colleague disapperad.
